What does three-way tap mean in practice?
The faucet conducts hot, cold and filtered water through separate channels to a common spout, without the need for an additional hole.
When does it matter?
Not every model maintains complete internal separation, so design and compatibility with the pressure system must be checked.
Which solutions are related to it?
A faucet with appropriate connections and separate filtered water control is selected, and the pipes are rinsed after installation.
